Application

Carboxylic acid-poly(ethylene glycol)-b-poly(lactide-co-glycolide) is a functionalized, amphiphilic, diblock copolymer composed of a hydrophilic PEG block and a hydrophobic PLGA block. These biodegradable, biocompatible polymers can self-assemble to form nanoparticles, such as micelles and polymersomes, in both aqueous and non-aqueous media. Due to these properties, these polymers are widely used in polymeric nanoparticle formulation to achieve controlled and targeted delivery of therapeutic agents (e.g. APIs, genetic material, peptides, vaccines, and antibiotics). The carboxylic acid functional group on the PEG chain enables rapid and facile surface functionalization, allowing for these materials to be used in applications such as targeted drug delivery.

Nitroglycerin (NTG) markedly enhances nitric oxide (NO) bioavailability. However, its ability to mimic the anti-inflammatory properties of NO remains unknown. Here, we examined whether NTG can suppress endothelial cell (EC) activation during inflammation and developed NTG nanoformulation to simultaneously amplify
